. ed to the pin elevating ried by said inner end will bear upwardly against that portion of the arm 6 between the pivot lugs 4C. and 5, and thus the pin carrying arm swings upwardly Jfrom the pivot lug 5, which now performs the function of a fulcrum and nthus the coupler pin is elevated to free the knuckle.

It will be noted that in'my improved uncoupling mechanism, buttwo operating parts are utilized and therefore the liability of the mechanism getting out of order and becoming inoperative is reduced to a minimum.

The actuating lever is operatively connectarm at a point prefer ably midway between the pivot lugs which Jform nlcrums for said elevating lever, and the pivot point of said actuating arm is Llocated immediately adjacent to the pivot lugs. By such arrangement the pin elevating arm can be elevated with the application of lcompamtively` little power Ato the outei` end of the actuating lever.

It will be readily understood that minor changes in the size,`orm and construction of the various parts oit my improved uncoupling mechanism can be made and substituted for those herein describedwithout departing from the spirit of my invention, the scope of which is set forth in the appended claims.

I claim:

1. In an uncoupling mechanism, a pin engaging arm, two lined ulcrums therefor` an actuating lever coperating with said arm, which lever has a fixed ulcrum.

2a. In a car uncoupling mechanism, a pin engaging lever having a pair of ulcrums, and a ulcrumed actuating lever operatively connected to the pin engaging lever between the ulcrnms thereof.

yfixed -fulcrunn 3. Ina car uncoupling mechanism, a pin engaging lever, a pivot lug against which the under side of the arm engages, a second pivot lug against which the upper side oi the arm engages, and an actuating lever operatively connected to said arm between the pivot lugs.

et. The combination with airail-way car body, and coupler, having aloclringl pin, of an armconnected to said locking pin, a pair of' pivot lugs for said arm, and an actuating lever operatively connected withA said arm between said pivot lugs, which lever :has a 5. yThe combination with a car body, and a coupler having a locking pin, of a pin engaging arm having two fixed ulcrums, and a ulcrumed actuating lever coperating with said pin engaging arm.

G. The combination with a car body,and a coupler having a. locking pin, of a pin engaging arm above and one below said arm, and a fulcrumed` actuating lever cooperating with said pin engaging arm.

7. An uncoupling mechanism comprising an arm, fixed pivot lugs engaging said arm on opposite sides to form a pair of ulcrums for said arm, and means having a Crum engaging said arm for swinging the same upon either one of the pivot lugs.

8. A two-part uncoupling lever, one of which parts has two fixed ulcrums and the other part having a single {ixed ulcrum.

In testimony whereof I hereunto affix my signature this third day oApril, 1912.
